Hope vs Hopeless

I sometimes wonder “shall I continue with the biggest thing in the world – HOPE” or shall I consider myself hopeless?

Some people exist in the world who “cannot” stay happy even with the happiest thing in their lifes (90%) on the other hand some people (only some 10%) are content with what they have, I know its always good to look for more for being successful but not at such an extent where you cant stay happy with almost everything in your life.
